It's just a guess, but I suspect that the pertinent people involved needed some research money, so they created a possible catastrophe. We don't live with our livestock in the house, so they had to be certain that we would suffer economic ruin if the third world was decimated. Those people haven't even seen our products, and if they did, what are they going to do? Trade us some diseased livestock? Having been through acid rain and numerous other scares that have never been resolved, I have become somewhat jaundiced about every new and world destroying problem that arises on a continuous basis. Feed the crisis lots of money, and it invariably disappears from the front page of the media.
